servicing pump. Electrical supply MUST match pump’s nameplate specifications. Incorrect voltage can cause fire, damage motor and voids warranty. Single phase motors are equipped with automatic thermal protectors which open the motor’s electrical circuit when an overload exists. This can cause the pump to start unexpectedly and without warning. Some models are equipped with a 3-prong grounded plug and MUST be used in a grounded 3-wire receptacle. DO NOT modify the plug or remove the ground prong. • Where cables must be spliced or connected to the motor leads, splices MUST be water tight. Commercially available potting or heat shrink kits may be used, if allowed by local or federal regulations. NOTICE: FOLLOW THE SPLICE KIT MANUFACTURER’S INSTRUCTIONS. • Where wire splices are used, follow one of these procedures: • Butt join the wires using properly sized and correctly crimped Sta-Kon™, or equivalent, connectors. Insulate and water proof each joint using heat shrink tubing equipped with a self contained sealer. Apply heat evenly from a torch until adequately sealed. OR • Use plastic insulators and a neoprene gasket sleeve set with properly sized and correctly crimped Sta-Kon™ connectors. Place a cap and gasket on each wire end, center insulator body over splice, insert the sleeve into the body as far as possible, hand tighten caps. • In the case of multiple conductors, stagger the joints. WARNING Hazardous voltage FAILURE TO PERMANENTLY GROUND THE PUMP, MOTOR AND CONTROLS BEFORE CONNECTING TO ELECTRICAL POWER CAN CAUSE SHOCK, BURNS OR DEATH. Operation • If the unit has been stored for an extended period, check the oil level in the motor and seal chamber, to insure that they are full, using the following procedures: • Motor Cover – With the pump in the upright position, remove the oil fill plug (358E), being careful that nothing enters the motor. The oil level should be above the top of the motor. With the correct oil fill as required. DO NOT over fill. • Cable Gland Assemblies – Re-torque both the power and sensor cable glands to values given in step 10 of “POWER CABLE REPLACEMENT”. • Before lowering the pump(s) into the containment area, three phase units should be jogged to insure correct rotation. See the motor rotation arrow on the motor cover (341). Check both pumps in a duplex operation. NOTICE:MOTOR STARTUP TORQUE, “KICKBACK”, WILL CAUSE THE MOTOR TO TWIST IN THE DIRECTION OPPOSITE ROTATION. INSURE THAT THE PUMP ASSEMBLY IS ADEQUATELY RESTRAINED. ! DANGER Hazardous Machinery DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY. NOTICE: DO NOT SWITCH PRIMARY POWER LEADS COMING INTO A THREE PHASE DUPLEX CONTROL PANEL, THIS WILL REVERSE ROTATION OF BOTH PUMPS. • If the three phase motor(s) rotation is backwards, reverse any two pump power cable leads at the pump control panel. MOTOR OVERHEAT/OVER WARNING CURRENT SENSING DEVICES Hazardous AUTOMATICALLY RESTART THE machinery MOTOR UNEXPECTEDLY AND WITHOUT WARNING. THIS CAN CAUSE SEVERE PERSONAL INJURY. • After installing the pump into the containment area, with adequate submergence, open the discharge valve fully. Start the unit using manual controls. If flow is appreciably less than rated performance, pump may be air bound. To expel trapped air, jog the unit several times, using the manual controls. • Have a qualified electrician take current measurements on the single or all three phases. Record these readings in the space provided in the “OWNER’S INFORMATION” section of this manual for future reference. • The unit is now ready for normal operation. Place the controls in the automatic position. Maintenance WARNING Hazardous voltage FAILURE TO DISCONNECT AND LOCKOUT ELECTRICAL POWER BEFORE ATTEMPTING ANY MAINTENANCE CAN CAUSE SHOCK, BURNS OR DEATH. UNIT MUST BE FLUSHED AND WARNING DISINFECTED, INSIDE AND OUT, PRIOR TO SERVICING. Biohazard can cause serious personal injury. Periodic Maintenance NOTICE: ROUTINE PERIODIC INSPECTIONS ARE REQUIRED AND SHOULD FOLLOW THE FREQUENCY AND MAINTENANCE SCHEDULE PROVIDED. FREQUENCY REQUIRED MAINTENANCE MONTHLY • Duplex Units – Check for even operating times. Uneven operation times indicate a defective unit, float switch or control. • Unimpeded float operation. Disassembly/Assembly Disassembly/Assembly WARNING Hazardous voltage FAILURE TO DISCONNECT AND LOCKOUT ELECTRICAL POWER BEFORE ATTEMPTING ANY MAINTENANCE CAN CAUSE SHOCK, BURNS OR DEATH. NOTICE: FOLLOW ALL SAFET...
